No Sound - IDT High Definition Audio CODEC (Windows Vista)

    Question

  • I no longer have sound. When I click on the sound icon, I see "VOLUME 0, speakers, IDT High Definition Audio CODEC." When I right click and select "Open Volume Mixer," I get the error box that reads, "No audio device installed." When I look in the device manager (control panel | device manager | Sound, video and game controllers), the IDT High Definition Audio CODEC device indicates that it is working properly and is enabled.

    You can open troubleshooting from control panel, click on Hardware and Sound->troubleshoot audio playback. Please tell us the result.

    If system restore doesn't work, please download the latest Audio driver from Dell's download website. After that, uninstall the previous driver and install this one to check the result.

  • if you can remember when it started, run a system restore and restore your computer to a day before the problem started.

    to run system restore:

    start> at the search box, type system restore

    or

    start>programs>accessories>system tools> system restore
